4.Remove the engine air in baffle located on the left- hand side of the battery compartment. Two M6 screws are located on top of the baffle and two M6 screws are located on the inside of the baffle towards the back.

5.Remove the small hose clamp and hose from the fuel regulator. It may be necessary to pry the hose off of the brass fitting using a screwdriver to gen- tly lift up the hose edge.

6.Remove the small brass hose fitting from the reg- ulator casting.

7.Place the small fuel jet, thread side first, into the threaded hole originally occupied by the brass hose fitting (Figure 1.4).

◆1.9.1 GENERATOR

Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air is always available. Consider these factors:

• Install the unit where air inlet and outlet openings

will not become obstructed by leaves, grass, snow,

etc. If prevailing winds will cause blowing or drift-

ing, consider using a windbreak to protect the unit.

• Install the generator on high ground where water

levels will not rise and endanger it.

• Allow sufficient room on all sides of the generator

for maintenance and servicing. A good rule is to

allow three feet of space on all sides.

• Where strong prevailing winds blow from one

direction, face the generator air inlet openings to

the prevailing winds.

• Install the generator as close as possible to the fuel

supply, to reduce the length of piping.

• Install the generator as close as possible to the

transfer switch. HOWEVER, REMEMBER THAT

8.Using a short No. 2 Phillips screw driver, thread the small fuel jet into the regulator casting. Do not over tighten.

9.Apply thread sealant to the threads of the hose fit- ting and replace it into the regulator body.

10.Re-attach the small hose and hose clamp and tighten as necessary.

11.Replace the engine air in baffle using the four M6 screws.

12.Identify both brass adjustment screws on the reg- ulator.

NOTE:

One adjustment screw can be accessed from the front of the unit and the second can be accessed from the back of the unit enclosure by removing the plastic hole plug. The screw can be turned with a long flat blade screwdriver.

13.To adjust the system to run on LP fuel, turn BOTH adjuster screws 1/2 TURN CLOCKWISE. The system should now be set for maximum power and best perfomance. DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE SET PINS FROM THE REGULATOR HOUSING. THIS WILL VOID THE WARRANTY.

LAWS OR CODES MAY REGULATE THE DIS-

TANCE.

◆ 1.9.2 TRANSFER SWITCH

1.9.2.1 7 kW, 12 kW and 15 kW Units

Transfer switches for use with these generators are sold separately and can be purchased from Generac Authorized Dealers.

•Install the transfer switch on a firm, sturdy sup- porting structure.

•To prevent switch distortion, level the switch if nec- essary. This can be done by placing washers between the switch enclosure and mounting sur- face.

•Never install the switch where water or any corro- sive substance might drip onto the enclosure.

•Protect the switch at all times against excessive moisture, dust, dirt, lint, construction grit and cor- rosive vapors.

•Failure to utilize a Generac transfer switch with this generator may void the warranty.
